It seems so obvious when you think about it - if your sound card has a lot of high-ESR caps on it, since it plugs into the PCI slot of your motherboard, it WILL DEFINITELY impact video playback a LOT!
Case in point, my ASUS CUR-DLS dual CPU P3 board had a working sound card but playing youtube or movie trailer video in full screen mode gave jerky stuttering results.
No caps on the Sound Blaster video card were leaky or bulging, but I checked ESR and found that every one of the 4.7uf 5v caps gave a reading of about 5. In fact, all of the lower uf caps had very high ESR readings (3 or higher)..
Got some new caps, recapped the sound card and the jerky video completely went away! Able to play full-screen even with the infamous onboard Rage chipset.
Hard to find the "little" caps in low-ESR series, and since the original card used 85C caps, I replaced with M-series Panasonics, much larger than the originals.
I'll bet a lot of boards with integrated sound suffer the same degradation because of crappy caps in the audio circuit.
Like my 800FSB IBM with 3.0Mhz hyper-thread CPU - video is terrible. The board is littered with 85C caps, presumably for the sound! I modded a small fan onto the Northbridge heat sink to keep the temps down. Hardinfo shows CPU temp of 78C, board has no hardware monitor settings itself. Looks like a full-recap job is called for!
I'll go 105C all the way on this one.
